摘要: Abstract We deal with the restoration of grey level images corrupted by additive independent Gaussian noise. The noise variance is unknown but a signal-to-noise ratio must be given. start technique proposed S. Geman and D. [1]. spatial interaction described Markov Random Field whose energy chosen in order to preserve edges. This parameterised. An estimation method parameters that performed before restoration. whole procedure illustrated on simulated Nuclear Magnetic Resonance images.
